More than half of the women cited in AWID’s 2017 tribute to female activists were murdered for defending their rights. Among the women killed are those who fought to protect their land from the state and multinational companies, or called out injustices or corruption, or stood up for the rights of lesbian, gay and transexual people.

While thousands of men defend human rights, women face particular challenges for their activism. They are targeted for who they are, as women, not just because they are protesting. In countries that view a woman’s role as being in the home, female human rights defenders are more prone to attack than men because they are seen as breaking social norms.

To mark international Women Human Rights Defenders’ Day on Wednesday, we honour some of the women who have been killed this year.
